At the 2010 Beijing Auto Show (Auto China 2010), Hyundai Motor Co. unveiled its all-new 1.6L Gamma GDI (gasoline direct injection) engine; the latest edition of its 3.3L Lambda V-6 engine with GDI; and staged the world-premiere of its all-new Verna subcompact. The company also displayed its new 8-speed automatic transmission.
Gamma 1.6L GDI. The new Gamma 1.6L is the smallest Hyundai engine yet to benefit from the application of Gasoline Direct Injection technology. The inline four develops 140 ps (138 hp, 103 kW)—a 13% improvement over a conventional Gamma 1.6L fed by multipoint fuel injection (MPI).
The new Gamma features a 150-bar direct injection fuel system, Dual Continuously Variable Valve Timing (DCVVT), a Variable Induction System (VIS) and anti-friction coatings such as CrN Physical Vapor Deposition (PVD) coating and Diamond Like Carbon (DLC) coating.
VIS delivers variable air flow based on speed conditions. At low and high speeds, air flows through the short runner, and at mid-range speed it flows through the long runner, helping optimize engine performance over the entire operating range.
Water jacket inserts help maintain a stable temperature balance between the upper and lower blocks.
New Lambda V-6 GDI. The latest edition of the Lambda V-6 engine delivers more power while lowering fuel consumption and emissions. Featuring a 150-bar gasoline direct injection fuel system, Dual Continuously Variable Valve Timing (DCVVT), and an optimized low-weight crankshaft design and exotic coating technologies on the piston skirts, piston rings and tappets to reduce friction losses, the new 3.3L engine produces maximum power of 300 ps (296 hp, 221 kW)—14.5% more than a comparable displacement engine equipped with MPI).
Hyundai will apply GDI to other members of the Lambda engine family including the 3.8L and one other new displacement which remains to be revealed.New Verna. The new sub-compact, Hyundai’s third China-exclusive model, is built on an all-new platform at the company’s plant in Beijing and is targeted at China’s strategically important C1 segment.
Verna is powered by the new generation Gamma gasoline engine with multiport fuel injection. Featuring all-aluminium construction for weight-saving, the 1.6L DOHC Gamma delivers 90.4 kW (121 hp) @ 6300 rpm and 155 N·m of peak torque @ 4200 rpm through a four-speed automatic transmission.
The base Verna is offered with the 1.4L DOHC edition of the Gamma which puts out 78.7 kW (106 hp) and 135.4 N·m and comes with the choice of a five-speed manual gearbox or four-speed automatic. Fuel economy is rated 5.7 L/100km (41 mpg US) with the manual; 6.2 L/100km (38 mpg US) with the automatic (1.4L with Fuel Economy Package).
The engine features Continuously Variable Valve Timing, a smart alternator and air conditioning compressor plus the adoption of motor-driven power steering.
The Verna will go on sale in the second half of this year. Hyundai will launch it in the Chinese market first, then gradually introduce it to other regions.
